• Manage employee benefit enrolments, eligibility updates, and terminations in the HRIS and with the vendors. 

• Ensure accurate payroll deductions, employer contributions and vendor billing reconciliation. 

• Partner closely with external benefits brokers, vendors and administrators to ensure smooth plan operations. 

• Assist with US open enrolment including employee communications and benefit materials. 

• Monitor benefits-related compliance activities by coordinating data and documentation with brokers and external providers (e.g., ACA reporting support, ERISA documentation, Form 5500 inputs). 

• Serve as a point of contact for employees regarding benefits questions and issue resolution. 

HR Generalist and employee lifecycle support 

• Support core HR processes for US employees, including onboarding, offboarding, and job changes.

HR data and systems 

• Ensure the accuracy, completeness, and integrity of HR and benefit data. 

• Use Excel and HR systems confidently to manage data, validate inputs, reconcile discrepancies and prepare routine reports. 

• Identify opportunities to improve HR processes, reduce manual work, and increase efficiency through better data practices and system usage. 

• Support basic recurring People Operations reporting needs. 

Employee experience & engagement 

• Support employee experience initiatives related to benefits, onboarding, and key employee lifecycle moments. 

• Assist with internal communications related to People initiatives and benefits programs.
